Effects of different levels of Brachiaria decumbens diets on in vitro gas production and ruminal fermentation
Although B. decumbens is abundant in the tropics, the utilization of this grass is limited due to the presence of steroidal saponins. Therefore, the main objective of this study was to determine the effects of different levels of B. decumbens diets on the in vitro gas production and ruminal fermenta...
